Application December 8, 1937, Serial No. 178,801

, Renewed June '29, 1939 i 4 Claims. (01. 43 147) My invention relates to insectexterminators. An important object of the invention is to provide apparatus of the above mentioned char acter for exterminating'insects, such as the boil 1 weevil, by firstspraying the cotton plant with Water followed by spraying the same with a powdered insecticide, such as arsenic. f

A further object of the invention isto'provide apparatus of the above mentioned character which will spray the powdered insecticide in an upward direction so that the powder willbe applied, to a considerable extent, to the lower surfaces of the leaves, to avoid the powder, being washed off by the rain, as much as possible.

-A' further object of the invention is to provide apparatus of the above mentioned character which may be drawn down a row of plants and will operate automatically both in spraying water and in spraying the powdered insecticide.

A further object of the invention is to provide apparatus of the above mentioned character which may be applied to a cultivator.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawing forming a part of this application and in which like numerals are employed to designate like parts throughout the same, v

Figure 1 is a side elevation bodying my invention,

Figure 2 is a perspective view of the same, Figure 3 is aside elevation of the insecticide hopper, parts in section,

Figure 4 is a transverse section taken on line of apparatus emdesignates a traction wheel, suitably connected with the {stock I and preferably equipped with a pneumatic tire. This traction wheel has a sprocket wheel l mounted to turn therewith.

Mounted upon one side of the beam 5 near its forward end isa water spraying pump including a horizontal cylinder H, having a plunger 12 reciprocating therein. This plunger is operated by a horizontal reciprocatory rod Hi, the rear end of which operates in a guide I 4, rigidly attached to the same side of the beam 5 with the cylinder H. An outlet pipe I5 is connected with the forward end of the cylinder II and extends down- ;or the like.

wardly beyond the cylinder in a substantially vertical direction and is then bent upwardly and laterally, as shown at l6 and is equipped with a spraying nozzle 11. "Water is supplied to the top of the cylinder I I near its forward end, by a pipe l8,xleading into the cylinder l I and an adjustable valve I9 is connected in the pipe I 8 to regulate the spray of water. The pipe l8 extends longitudinally of and above the beam 5 and leads into the bottom of a vertical water tank 20, suitably supported upon the handles" H by a strap 2| Acompressed air supply pump is provided and mounted upon the opposite side of the beam 5 with respect to the cylinder H and near the forward end of the beam. This compressed air supply pump includes 'a horizontal cylinder 22, mounted upon the beam 5. A plunger 23 is mountedto reciprocate within the cylinder 22 and is moved by a reciprocatory rod '24 extending longitudinally of and above the beam 5. Connected with the forward end of the cylinder 22 is a pipe 25, extending rearwardly, and having its discharge end connected with a T-coupling 26. The opposite end of this T-coupling is connected with a pipe 21, extending downwardly in a vertical'direction, as shown at 28 and then bent upwardly and'carrying a spraying nozzle 29. The vertical arm 30-01 the T-coupling leads into the lower end of a vertical chamber 3!, and this chamber is attached to the bottom of a hopper 32, for holding the powdered insecticide, such as powdered arsenic. The hopper 32 is mounted upon the beam 5 by any suitable means, such as by a strap 33. r

Extending transversely within'the chamber 3| is a horizontal rock shaft 33, having a disc valve 34" rigidly mounted thereon. When this disc valve is in the horizontal position, it has substantially an air tight fit within the chamber 3! and therefore seals or covers the lower portion of the chamber. When tilted from the horizontal position, it will fill the lower portion of the chamher 3! with the powdered insecticide. Connected with the outer end of the rock shaft 33' is a crank 35, carrying a pin 36, adapted to operate within an elongated slot 31 formed in a vertically swinging lever '38, pivoted between its ends at 39, upon, the stationary bracket 40, rigidly mounted upon the beam 5. I

The upper end of the lever 38 isprovidedwith a finger 4|, hinged thereto at 42 and swung in one direction by a spring 42' and adapted to brake forwardly only. The finger 4| is forked to receive the reciprocatory rod l3 which operates the plunger H of the water pump. This rod has a trip 43 rigidly secured thereto. The lever 38 is returned to the normal starting position, to close the disc valve 34, when released, by a spring 44.

The means to operate the plungers l2 and 23 comprises a transverse rotary shaft 44, suitably mounted upon the rear end of the beam 5, and this shaft is equipped with a sprocket wheel 45, rigidly mounted thereon, and driven by a sprocket chain 46, engaging the sprocket wheel ID, A crank 41 is rigidly mounted upon one end of the shaft 44 and has pivotal connection with a connecting rod 48, extending forwardly for connection by means of. a universal joint 49, with the rod l3. A crank 53 is rigidly mounted upon the shaft 44 and has pivotal connection with a connecting link 5i connected with the rod 24- by a universal joint 5|. The cranks 41 and 5B are disposed at from each other. When the plunger [2 is in the forwardmost position, the

plunger 23 is in the reannost position. The cyl-, inders II and 22 and the rods l3 and 24 extend longitudinally of the beam 5. i

The operation of the apparatus is as follows.

The machine is drawn down between two rows of cotton plants or the like and travels upon one side of a given row, and the nozzles H and 2t travel near the ground and are directed upwardly and laterally toward the row or" plants being treated. As the machine travels down the row, traction wheel 9 rotates turning shaft 44,which causes the plungers l2 and '23 to reciprocate, as is obvious. When the plunger 12 is in the rearmost position and during its forward and rearward movements, water is supplied from the pipe 18 into the cylinder 5 l the amount of water being regulated by the adjustment of the valve l8, so that the water is supplied in a small stream. Upon the rearward movement of. the plunger i2, air will be drawn into the cylinder H through the pipe l5, and when the plunger l2 moves forwardly, this air, with the water, the cylinder I! being only partly filled with water, will be forced through the pipe I5 and the water sprayed through the nozzle ll. When the plunger [2 is in the forwardmost position, the plunger 23 is in the rearmost position, and the valve disc 34 is in the closed position and air has been drawn into the cylinder 22. When the plunger 12 starts upon its rearward movement, trip 43 engages the finger 4i and the lever 38, turning the upper end of the lever 38 rearwardly, and this lever and associated elements tilt the disc valve 34 so'that the powdered insecticide passes into the lower end of the chamber 3!. By the time the plunger l2 moves a short distance rearwardly, the trip 43 disengages finger 4! and the spring 44 quickly returns the lever 38 to the normal position closing valve disc 34. As the plunger I2 continues to move rearwardly, the plunger 23 is moved forwardly. The plunger 23 will compress the air in the cylinder 22 and force the same through the pipe 25 into the coupling 26 and through the pipe 28 and through the nozzle 29. The powdered insecticide within the lower end of the chamber 3| will drop into the horizontal arm of the coupling 26, and also will be drawn into the same by the suction action of the air traveling through the pipe 21. The powder and the air is therefore sprayed through the nozzle 29.

My machine is so arranged that the water is first applied to the leaves of the plant, upon the under surfaces of the leaves to a considerable extent and the powdered insecticide is then sprayed upon the wet leaves, upon their lower surfaces, to a considerable extent. This will insure that the powdered insecticide will adhere to the leaves and will not be readily washed off by the rain.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes in the shape, size, and arrangement of parts, may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims.

Having thus described my invention, I claim:
